Condensers
It is more common, however, for a water-cooled condenser to be connected to a
cooling tower.
In this case, typical methods for modulating the water flow through the
condenser include either using a variable-speed drive on the condenser water
pump or using a diverting valve and pipe to bypass the condenser. The
variable-speed drive on the pump modulates the amount of water pumped
through the condenser. The diverting valve modulates the water flow through
the condenser bundle by diverting some of the cooling water around the
condenser through the bypass pipe, directly back to the cooling tower.
Each of these options has the effect of varying the flow rate of water through
the condenser, ensuring an acceptable condensing pressure and temperature.
Another method of controlling the capacity of a water-cooled condenser is to
vary the temperature of the water entering the condenser.
